My recently bought Jetta 2.0 TFSI is equipped with DSG automatic transmission.

It really feels good not feeling any gear shifting while in acceleration (wow!).

Now, one thing that surprised me. The other day, I had to drive up a few floors to park my car (3F) at a closeby department store. There were many customers thus many cars trying to park there. While going up, I came to a stop between 2F and 3F because cars were waiting in line. When it came for me to move up I took my foot off the brake and before getting to press the accelerator my car started slipping back.

If it's automatic, even if I take off my foot from the brake, shouldn't it at least NOT slip backwards? (I mean, my previous car held it's stand while in this same situation)

Or is this normal because of how DSG automatic transmission is built?

It felt like I had manual transmission and had to quickly press on the accelerator so to avoid rolling backwards on a hill.
